$41,354.98
Explanation:
Required future worth = Annual savings x FVIFA(r%, N) x (1 + r)
Required annual savings ($) = [Required future worth / FVIFA(r%, N)] / (1 + r)
= 725,000 / [FVIFA(10%, 10) * 1.1]
= 725,000 / (15.9374 * 1.1)
= 725,000 / 17.53114
= 41354.98318991235
= $41,354.98
Note: Since this is annuity due (deposit made at beginning of year), FV is divided by (1+r).
